how to convert 1e+11 into number? - Mathematics Stack Exchange In your example the string "1e+11" means the number $1 \cdot 10^ {+11} = 10^ {11} = 1\underbrace {00000000000}_ {11 \, "0" \mbox {symbols}}$ Note that the resulting number is given by a string as well, just a usually more familiar one, the base 10 positional system representation learned in school
linear algebra - How to tell if a set of vectors spans a space . . . @Javier: By definition, the rank of a matrix is the dimension off the span of its rows (which is equal to the dimension of the span of its columns); elementary row operations do not change the row space, so doing Gaussian elimination does not change the rank, it only makes it easier to tell what the rank is (if you are doing it correctly, at any rate) In summary: yes, because you are
1 8, 1 4, 1 2, 3 4,7 8英寸分别是多少厘米? - 知乎 把1英寸分成8等分: 1 8 1 4 3 8 1 2 5 8 3 4 7 8 英寸。 This is an arithmetic sequence since there is a common difference between each term In this case, adding 18 to the previous term in the sequence gives the next term In other words, an=a1+d (n−1) Arithmetic Sequence: d=1 8
